200 Gauge

  • Gauge is a measure of film thickness. 55 gauge is thin and 200 gauge is thick.
  • Thinner gauges shrink more easily and wrap more packages per roll.
  • Thicker gauges are for wrapping heavy products or items with sharp edges.
  • Thicker gauges give a more premium feel to your packaging and offer stronger protection.

Helpful Hints

SHRINK FILM

  • All film is centerfold, so film comes folded in half lengthways on rolls.
  • How to find the film width you need:

CENTERFOLD

For rectangular items:

  1. Add the width and height.
  2. Add 2" for shrinkage.
  3. Round up to the next whole number.

Example: 12" L x 8" W x 3.5" H box

  • 8" W + 3.5" H = 11.5"
  • 11.5" + 2" = 13.5"
  • 13.5" rounds up to 14"

Result: 14" film width is required.

For round items:

  1. Multiply the diameter by 3.14.
  2. Multiply by 1.1 to add 10% for shrinkage.
  3. Divide the result by 2.
  4. Round up to the next whole number.

Example: 5.5" diameter candle

  • 5.5" diameter x 3.14 = 17.27"
  • 17.27" x 1.1 = 18.997"
  • 18.997" ÷ 2 = 9.4985"
  • 9.4985" rounds up to 10"

Result: 10" film width is required.

  • Centerfold film must be sealed on 3 sides around the product before shrinking.
  • To determine mil thickness, divide gauge by 100.
    • For filmWidthExample, 75 gauge ÷ 100 = 0.75 mil
  • PVC – The smallest amount of shrink and lowest sealing temperature make PVC easy to work with.
  • Economy Polyolefin – Best value. FDA compliant for direct food contact and puncture resistant.
  • Deluxe Polyolefin – Best for odd-shaped items. It shrinks in all directions and offers the finest presentation.

BUNDLING SHRINK FILM

  • All film is single wound, so film comes unfolded on rolls.
  • Use to bulk pack heavy goods, such as cleaning supplies or water bottle packs.
  • Widely used with automated packaging equipment with integrated heat tunnels.
  • All of Uline's bundling film is 200 gauge polyethylene, which is up to 3 times stronger than standard shrink films.
